Where are the chapters at then? This is a common thing. A series doesn't get updated for a while, somebody picks it up, then all of a sudden the original translator/scanlator pops up like "Hey, what gives, I was just about to release an update!" Cool story bro, release it then. Personally I like competition in the community. Look at Reaper and Asura, if you know them. They basically translate the exact same series. If one picks up a series, the other is almost guaranteed to pick it up too. Kinda hilarious really, but they both have loyal fan bases and they both release fast af, probably trying to out do the other.
If you feel like your work isn't good and don't want to continue, that's your prerogative. But don't let anybody, outside of a legit DMCA order, move you off doing something you want to do. If you enjoy the scanlating/translating process, have at it. This series was effectively dropped. Do as you see fit.
Edit: What's truly crazy about this, after checking the chapters, it seems Harufloyd sniped this from Snow_Snow unless they asked before hand. Which they might've. But if he/she didn't, how you gonna complain about sniping when you sniped the series yourself? Again, I dunno if that's the case, conversations may have been had behind closed doors. But if not, hilarious.
